Purpose. To evaluate the change in the functional activity of retinal ganglion cells (RGCs) in response to intraocular pressure (IOP) drop in patients with newly diagnosed early stage primary open-angle glaucoma (POAG) using a pattern electroretinogram (PERG). Material and methods. A prospective non-randomized cohort study included 12 patients (24 eyes) including 5 men, 7 women, aged 63.42 ± 2.96 years with newly diagnosed early stage POAG in at least one eye, who underwent PERG (Diopsys Nova, Diopsys, Inc.) in addition to an ophthalmologic examination. After being diagnosed with POAG, all patients were prescribed prostaglandin analogues as monotherapy. One and four months into the treatment, repeated examinations took place. Results. At these time points, a significant decrease in IOP was noted, accompanied by an increase in PERG parameters , which indicates an improvement in the functional activity of RGCs, yet no linear relationship between the IOP decrease and the improvement in PERG parameters could be found. Conclusion. Early stage naïve-treatment POAG patients with minimally impaired visual fields as determined by threshold computer perimetry may have their RGCs functional activity partially restored and IOP lessened thanks to continuous IOP-lowering therapy with prostaglandin analogues. PERG can be used as a method for evaluating the effectiveness of glaucoma hypotensive therapy in terms of maintaining and improving the functional activity of RGCs.

Adenoviral conjunctivitis (AVC) is treated with pathogenetically determined immunotropic drugs, the most commonly used of which are combined eye drops that include recombinant human interferon alpha-2b and diphenhydramine hydrochloride. In 2020, Russia registered the first domestic generic of the original, called Interferon-Ophthalmo eye drops. Purpose: to compare the effectiveness and safety of InterferonOphthalmo and the original interferon alpha-2b + diphenhydramine drug (Ophthalmoferon) in AVC patients. Material and methods. The study included 30 patients (60 eyes) aged 18–75 years with a clinically confirmed AVC, divided into the main group and the control group, each having 15 patients. The main group received Interferon-Ophthalmo, while the control group received Ophthamoferon. The treatment procedures were identical, with the follow-up period of 15 days. Clinical manifestations of AVC were assessed according to multiple parameters: complaints of eyelid edema, eye redness, lacrimation, itching, foreign body sensation, severity of conjunctival edema and hyperemia, follicular reaction in the lower conjunctival fornix, and hemorrhages. Results. The comparative assessment of the proportion of cases of clinical recovery, performed on the 7th and the 15th days of AVC therapy, confirms the same effectiveness of the two drugs. Conclusion. Interferon-Ophthalmo has a high clinical efficacy comparable with that of the original drug Interferon alpha-2b + Diphenhydramine and can be recommended for the treatment of patients with adenoviral ophthalmic infections.

Purpose: to assess the biophysical properties of the sclera by measuring its acoustic density in keratoconus, highly myopic, and healthy eyes. Material and methods. We examined 34 patients (67 eyes) aged 15–45 with keratoconus of various stages, 15 patients (30 eyes) aged 17–28 with high myopia and 15 people (30 eyes) aged 28–37 without ophthalmic pathology. The acoustic density of the sclera (ADS) was measured on the Voluson Е8 ultrasound device (GE Healthcare, USA) in the posterior eye pole (ADS-1) and in the equatorial area (ADS-2). The axial length (AL) of the eye, corneal thickness (CT), anterior chamber depth (ACD), and lens thickness (LT) were determined using Galilei G6 (Ziemer Group, Switzerland). The vitreal chamber depth (VCD) was calculated according to the formula: VCD = AL – СT – ACD – LT. Results. In keratoconus patients, the average ADS-1 value was 242.5 ± 7.4 conventional units (CU), ADS-2 averaged 234.1 ± 12.1 CU, AL was 24.6±1.1 mm long, and VCD was 17.1 ± 0.4 mm. In high myopia group, the average value proved to be significantly lower: ADS-1 was 210.3 ± 15.7 CU, ADS-2 — 201.2 ± 11,2 CU, while AL and VCD were higher: resp. 27.0 ± 0.7 mm and 19.2 ± 0.5 mm (p < 0,05). In the control group (healthy eyes), ADS-1 was 247.5 ± 2.8 and ADS-2 was 238.1 ± 0.6 CU, which practically showed no difference to the keratoconus group (p > 0.05). AL was 23.7 ± 0.6 mm, and VCD was 16.0 ± 0.6 mm. An insignificant tendency toward ADS drop in keratoconus eyes with AL over 25.0 mm was observed. Probably, we are dealing here with a combination of keratoconus with axial myopia. Conclusion. The acoustic density of the sclera of keratoconus patients approaches the respective parameter of healthy eyes and is significantly higher than that of highly myopic eyes. The analysis of acoustic density of the sclera and vitreal chamber depth may be considered as a method of additional differential diagnostics of keratoconus and congenital myopia with high corneal refraction and astigmatism.

Purpose: to evaluate the effectiveness of combined treatment of chronic central serous chorioretinopathy (CSCRP) complicated by type 1 choroidal neovascularization (CNV) by subthreshold micropulse laser exposure (SMILE) and intravitreal injection of angiogenesis inhibitors ( IIAI). Material and methods. 37 patients (20 men and 17 women) with monolateral chronic recurrent CSCRP complicated by type 1 CNV, aged 35 to 57 (ave. 43.6 ± 6.7 yrs.) at the moment of first referral, were divided into two groups. The retrospective group included 15 patients (15 eyes) whose first phase of treatment consisted in IIAI (up to 5 injections with an interval of one month). Those who showed no treatment effect were given a SMILE procedure one day before the 6th injection. If neurosensory retinal detachment persisted, the combined treatment (SMILE + IIAI) was repeated monthly until the neurosensory retina could be fully attached, whereupon the patients were transferred to monotherapy with anti-VEGF injections, gradually increasing the interval between the injections. The main group included 22 patients (22 eyes), whose treatment began with a single IIAI. If no neurosensory retinal detachment resorption occurred, the patients received a SMILE procedure one day before the second IIAI injection. The combined treatment was repeated monthly until neurosensory retinal detachment completely resorbed, then the treatment continued with IIAI alone with a gradual increase of intervals between the injections. Results. The number of IIAI in the main group (5 to 8, ave. 6.1 ± 0.8) was significantly lower than in the retrospective group (8 to 10, ave. 8.8 ± 0.77). Best corrected visual acuity increased in both groups, but the main group showed a better central photosensitivity, which is associated with the faster reattachment of neurosensory retina. By the end of the follow-up period, the area of type 1 CNV, and the thickness of the choroid were significantly lower in the main group as compared to the retrospective group. The combined treatment did not cause a single case of complication. Conclusion. The proposed combination of laser exposure followed by IIAI is a safe method for treating complicated forms of CSCRP, which quickens the resorption of subretinal fluid and reduces the number of treatment procedures.

Purpose. To assess the clinical efficacy of the SRK II formula with a correction factor Rm in children with congenital cataracts who are at risk of pseudophakic myopia. Material and methods. A complex examination of 48 children (86 eyes) with congenital cataracts involved visometrics, tonometry, tonography, biomicroscopy, keratorefractometry, ophthalmoscopy, ultrasonography, and pachymetry. To determine the IOL power, we used the SRK II formula supplemented with the individual correction factor Rm, proposed by the authors. The examined children were divided into 2 groups. The main group 1 included 22 patients (42 eyes), for which the IOL power was calculated with the Rm factor. The control group 2 consisted of 26 patients (44 eyes) for which the IOL power was calculated according to the traditional SRK II formula using age-related hypocorrection of refraction but without the Rm coefficient. Results. The correction factor Rm, allowed us to achieve the targeted refraction in children who were at risk of developing pseudophakic myopia in 83.3 % of cases of the main group (versus 45.4 % of the control group cases) and reduce the development of high age-related refraction) by 37.9 %. In children of the main group, visual acuity reached, on average, 0.5 ± 0.001, while in the control group it was also higher but only reached 0.200 ± 0.001. Conclusion. The method of calculating the IOL optical power involving an individual correction factor Rm, according to the formula: SRK II – R – Rm can be recommended for clinical practice focused on children at risk of abnormal refractogenesis.

Purpose: to evaluate the expediency and efficacy of conservative therapy of patients with inactive stages of Graves’ orbitopathy complicated by optical neuropathy. Materials and methods. 62 patients with an inactive stage of Graves’ orbitopathy complicated by optical neuropathy were divided into two groups: group 1 (21 patients, 33.9%) received only symptomatic and local therapy, while group 2 (41 patients, 66.1%) additionally received periorbital injections of glucocorticoid drugs. The patients were examined clinically and instrumentally before and after treatment as well as after a long period of more than 12 months. Results. A positive clinical effect of treatment confirmed by positive dynamics of functional indices of computer perimetry (MS, MD) was achieved in 44 cases (71%), of which 33 patients (75.0% ) belonged to group 2. Positive changes in group 1 were achieved in 52.4% of cases and in group 2 in 80.5% of patients. Long-term results showed stable positive changes in 92.1% of cases. Conclusion. The need for complex therapy, involving local injections of glucocorticoid drugs, of patients in an inactive stage of Grave’s orbitopathy who develop symptoms of optical neuropathy was substantiated.

Purpose: to evaluate the effectiveness of approaches to tear substitution in dry eye syndrome (DES) patients before cataract phacoemulsification (CPE). Material and methods. 60 DES and cataract patients who received preoperative therapy — tear substitute instillations (4 times a day, 1 month), were examined before CPE. They were divided into 2 groups each of which was subdivided into two subgroups. Group 1 included 30 mild DES patients with lipid deficiency who had a negative lipid interference test, meibomian gland dysfunction (MGD), and aqua deficiency absence (Schirmer-1 test > 15 mm). The subgroup 1.1 (15 patients) received 0.18 % sodium hyaluronate (SH) instillations (Gilan comfort), while the other subgroup 1.2 received “fat-water” type emulsion instillations. Group 2 consisted of 30 moderate DES patients with lipid-aqua deficiency, who also had negative lipid interference test, MGD, and aqua deficiency presence. Subgroup 2.1 (15 patients) received 0.3 % sodium hyaluronate (SH) instillations (Gilan ultra comfort), while subgroup 2.2 patients received “fat-water” type emulsion instillations. We evaluated: the OSDI points, and tear break-up time (TBUT). Results. As a result of therapy, a positive effect of the therapy on OSDI and TBUT was observed in all subgroups. In group 1 , OSDI decrease and TBUT increase were more pronounced in subgroup 1.1 patients, however, this difference between subgroups was not statistically significant. In group 2, OSDI decrease and TBUT increase were more pronounced and statistically significant in subgroup 2.1 patients. Conclusion. In patients with mild DES and lipid deficiency, 0.18 % SH (Gilan comfort) demonstrated a positive effect on OSDI and TBUT comparable to the “fat-water” type emulsion. In moderate DES patients with lipid-aqua deficiency, 0.3 % SH (Gilan ultra comfort) demonstrated a statistically significant and more pronounced positive effect on OSDI and TBUT than the “fat-water” type emulsion.

Material and methods. 60 DES and cataract patients who received preoperative therapy — tear substitute instillations (4 times a day, 1 month), were examined before CPE. They were divided into 2 groups each of which was subdivided into two subgroups. Group 1 included 30 mild DES patients with lipid deficiency who had a negative lipid interference test, meibomian gland dysfunction (MGD), and aqua deficiency absence (Schirmer-1 test > 15 mm). The subgroup 1.1 (15 patients) received 0.18 % sodium hyaluronate (SH) instillations (Gilan comfort), while the other subgroup 1.2 received “fat-water” type emulsion instillations. Group 2 consisted of 30 moderate DES patients with lipid-aqua deficiency, who also had negative lipid interference test, MGD, and aqua deficiency presence. Subgroup 2.1 (15 patients) received 0.3 % sodium hyaluronate (SH) instillations (Gilan ultra comfort), while subgroup 2.2 patients received “fat-water” type emulsion instillations. We evaluated: the OSDI points, and tear break-up time (TBUT). Results. As a result of therapy, a positive effect of the therapy on OSDI and TBUT was observed in all subgroups. In group 1 , OSDI decrease and TBUT increase were more pronounced in subgroup 1.1 patients, however, this difference between subgroups was not statistically significant. In group 2, OSDI decrease and TBUT increase were more pronounced and statistically significant in subgroup 2.1 patients. Conclusion. In patients with mild DES and lipid deficiency, 0.18 % SH (Gilan comfort) demonstrated a positive effect on OSDI and TBUT comparable to the “fat-water” type emulsion. In moderate DES patients with lipid-aqua deficiency, 0.3 % SH (Gilan ultra comfort) demonstrated a statistically significant and more pronounced positive effect on OSDI and TBUT than the “fat-water” type emulsion.","PeriodicalId":36080,"journal":{"name":"Rossiiskii Oftal''mologicheskii Zhurnal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49138921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: to analyze social media messages of patients with neovascular age-related macular degeneration (nAMD) and diabetic retinopathy (DR), or their careers in order to investigates the patients’ opinion in the condition of real clinical routine. Material and methods. Real-life anonymized stories of patients from Russian-language open Internet sources (forums, social networks in Russia) were processed by artificial intelligence techniques: the technologies of automated analysis of unstructured natural language texts, including semantic technologies. In these messages, patients and their careers (mainly, family members) openly and in an ‘uncensored’ way share their experience in diagnostics and treatment while looking for a second opinion or supporting each other. They use general social networks as well as specific disease-related forums or Q&A portals. We identified 73 098 DR/nAMD-related posts, including 13 138 posts by 844 DR patients and 358 posts by 212 nAMD patients. The posts were analyzed in several steps with the technologies of automated analysis of unstructured natural language texts including semantic technologies aimed at processing large volumes of data. The semantic analysis of texts dealt with the whole meaning rather than individual keywords. Results. We obtained information on the patients’ characteristics and treatment plans of retinal diseases in real practice but also on the patients’ attitude to their condition, diagnostic and curative procedures, their needs and difficulties experienced during treatment. The nAMD and DR patients have a low level of Internet activity and poor awareness of these diseases as compared with the patients suffering from non-ophthalmological diseases with lower prevalence (breast cancer, multiple sclerosis, etc.) or other ophthalmological disorders. Most of the content for DR was produced by the patients’ relatives (82.6 % of messages), and for nAMD — by the patients themselves (65 %). The key item for DR patients was diabetic microvascular manifestations (over 42 000 posts discussed ‘diabetic foot’ and only 681 ‘diabetic retinopathy’). Quality of life (QoL) was shown to be significantly affected with inability to work as a major burden for 30 % of nAMD patients, and diabetes-associated comorbidities as a key factor compromising QoL in 20 % of DR patients. In nAMD patients, the average time-to-diagnosis after disease manifestation was 1 year (35 % patients reported 1–2 months), in DR, over a half of the messages mentioned 1–2 years. The key reasons for visiting the clinics included in-depth eye exams (OCT mentioned by 59 % of nAMD patients) and treatment (24.1 %). Only 33.2 % of nAMD patients and 7 % of DR patients noted that they received anti-VEGFs. Treatment unaffordability is one of the key barriers. The patients lack clear understanding of the prognosis and effective treatment options. Conclusion. The study revealed low activity and awareness of nAMD and DR patients with regard to their dise

Purpose: to describe the mechanisms of the therapeutic effect of platelet-rich plasma (PRP) components on the retina in macular hole (MH) surgery. Material and methods. The results of autologous PRP use in 36 cases of surgical treatment of eyes with idiopathic full-thickness MH sized 96 to 932 mm (ave. 546.4 ± 49.8 mm) are presented. Corrected visual acuity before surgery was 0.04 to 0.2 (0.09 ± 0.01). The quantity of cell elements in PRP fractions was determined using a hematological analyzer Sysmex XS-500i (Germany). Results: 2 months after the operation, all retinal layers in the MH area were found to restore in all patients, who showed an increase in visual acuity to 0.2–0.6 (0.40 ± 0.04). 35 patients (97 %) had no MH relapse over the 6-month post-surgery period. A technique was proposed to evaluate the quality of PRP by the presence of large platelets. The mechanisms of the therapeutic effect of PRP components on the retina were presented. Conclusion. The collection of data on the effectiveness of PRP components is instrumental in planning its wider use in the treatment of degenerative, infectious, post-traumatic and other disorders of eye structures. The evaluation of PRP quality by the content of functionally active platelets will also contribute to more effective PRP use in ophthalmology.

Purpose. To analyze the level of endothelin-1 (ET-1) in the tear fluid (TF) of children with primary congenital glaucoma (PCG) and to detect possible correlations between the clinical and the laboratory data. Material and methods. We examined 23 eyes of 15 children with PCG aged between 7 months and 15 years and 3 healthy fellow eyes of these children. 25 eyes of children of same age without glaucoma (somatically healthy with mild hyperopia and/or concomitant strabismus) served as control. A standard ophthalmological examination was supplemented by the flash visual evoked cortical potential, a total and a rhythmic electroretinogram, axial length (AL) echobiometry of the eye, optical coherence tomography of the optic nerve head, enzyme immunoassay (ELISA) of ET-1 level in TF were given. Results. In most children with PCG (95.6 %), the TF level of ET-1 (mean 9.69 ± 3.80 pg/ml) was higher than that in healthy children (4.65 ± 2,02 pg/ml) (p < 0.001). Increased levels of ET-1 (up to 8.90 pg/ml) were also detected in healthy fellow eyes of children with PCG. The mean level of ET-1 in children with PCG aged 3 to 15 years was significantly higher (p< 0.05) lower than in the initial stage. Our study revealed no correlations between the ET-1 level and the degree of retinal nerve fiber layer thinning, or the AL in children with PCG. Conclusion. For the first time, an increased level of ET-1 in the TF in children with PCG was revealed as compared to healthy children. A lower value of ET-1 in the far advanced PCG stage as compared to the initial stage can be explained by long-term chronic eye tissue hypoxia depleting the protective reserves of the eye. Since no obvious correlation between ET-1 level in the TF and clinical and functional data of children with PVG has been found, we cannot definitely view the ET-1 level in the TF as a measure of ischemia degree in PCG. Further studies are needed to obtain reliable correlations.
